Safety is the core of the railway transport [4].
Once the train speed reached 200km/h or more, even smaller disasters or accidents is also likely to lead to a major traffic accident on the railway, it seriously endanger the safety of state property and the lives of the passengers[7].
The train locomotive and 1-4 vehicles had derailed, the accident caused four deaths and 71 injured, Jiao Liu line interrupted traffic whole line.
It is a threat to railway lines and train traffic safety.
When monitoring specific work sites, we should be investigated local topography, environment, climate and safety level types to choose reasonable monitoring means. 2 home and abroad development status of the foreign matter invasion warning system With the growing national degree of attention on railway safety, related railway departments keep train safety as a priority and study the relevant safety technology as an important part of the high-speed railway construction.

Airport runway friction coefficient test vehicle is the key equipment to test the runway friction coefficient, it's test precision directly affects the safety of aircraft.

The results show that the bearing provides reliable measurement for traffic monitoring and enable to conceive details for the improvement of the output voltage of the PCGE.
Accordingly, active development and applications of structural health monitoring (SHM) systems for major bridge structures are continuously implemented as a tool to sustain such lifetime perspective in terms of safety, durability and performance not only for aging but also for newly-built structures [1].
However, the results showed lack of consistency to verify effectively the applicability of the PCGE for the measurement of traffic load.
Note that the traffic load is generally modeled in terms of the wheel loads represented as a series of concentrated load with definite spacing.

According to statistics, 70% of national highway traffic accidents are due to tire blowout, and a speed of more than 160km/h makes mortality possibility up to nearly 100%.
High-speed tire blowout is considered to be the super-killer of traffic safety.
And all the tire blowout incidents warn people to pay attention to tire safety. [1] Working Principle and Structure Design Method of Emergency Inflation System [2] Technology Route.
